member whereby any thickness of slices may be provided without changingthe "meat or any feature of the device except the feeding mechanism. Informing the carriage, a receiving portion is provided for receivmg theuncut meat, and a discharge or retaining portion is provided designed toreceive the slices of cut meat. On this discharge portion is arranged afilling or movable stop for holding the severed parts of the meat intheir original upright position .so that when he complete piece of meathas Be it known that I, Lnorono Limunwioa, a citizen of the UnitedStates, and a T051: dent of the city of New York, borough of Brooklyn,in the county of Kings and State of New York, have invented a new andImproved Meat-Slicer, of which the follow- This invention relates toimprovements in n'leatslicing devices, and has for an ob e(-.t toprovide an improved structure which Wlll quickly and uniformly cut orslice meat and retain the same substantially in a normal position duringthe slicing operation, so that the finished piece of meat will remainsubstantially in its original. shape though in slices.

A further object of the invention is to the-delivery portion of thecarriage in substantially the same position or shape as the originalpiece of meat before slicing.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1-is a side elevationof an embodiment of the invention; Fig. 2'is a top plan view of the structure shown in Fig. 1; Fig- 3 is a sectionthrough Fig. 1 on the line 33; Fig. 4 is a detail fragmentary erspectiveview showing the power cut-o or shifting mechanism; Fig. 5 1s afragmentary top plan View of the discharge portion and follower of thecarriage; Fig. 6 is a detail chine designed to out a piece of meat andcut the same in slices of any desired thickness without exposing thesides of the slices to the air, so that the meat will remain 1n acompact body after being sliced, and so retain its moist condition untilready for use.

A still further object of the invention more specifically, is to form adevice in which a reciprocating and oscillatingsup porting traveler isused, -together with a band knife for slicing the meat arranged on thecarriage, the parts being so arranged that the same may be adjusted forcutting of Flg. 5, the same being shown on an enlarged scale; Fig. 7 isan enlarged top plan view of the driving mechanism; Fig. 8 is afragmentary top plan view of a pair of knife guiding and centeringrollers and associated parts and Fig. 9 is a view'similar to Fig. 8,disclosing a pair of cleaning brushes.

Referring tothe accompanying drawings by numerals, 1 indicates a base onwhich are mounted a plurality of posts or uprights 2. On the 'u rights 2are arranged tracks 3 and 4 designed to engage suitable wheels 5 and 6,connected with the framework 7 of the carriage 8. The framework 7 isprovided with a pair of cross bars 9, :above ating automatically as lonas the power is. turned on, so that the entire piece of meat may besliced without stopping the machine.

In carrying out the objects of the invention, a carriage is provideddesigned to move back and forth or reciprocate on-suitable carriers on asuitable track. This carriage ber for the meat, or other article placedthereon so that the meat may be fed forward a given distance upon eachreciprocation or movement of the carriage. This feeding forward of themeat will allow the knife to sever the meat into slices and to cut aslice upon each movement of the carriage, the knife bein formed as adouble edged band knife. T e same power mechanism which qperates theknife is connected with the carriage for shifting the same back andforth, and with a feeding mechanism designed to feed the meat step bystep forwardly toward the knife. This feeding mechanism is formed withan adjusting 11, these side members being connected with the framework 7by suitable supporting brackets 12 and 13 (Fig. 3). On the frame 7 arearranged a pair of shafts 14 and 15, the shaft 15 being substantially anidler, but carrying a sprocket wheel 16 so as to properly support achain 17. The chain 17 also passes over a sprocket 18 vri 'dly securedto the shaft 14, by which it 1s driven been sliced, t e same will bearranged on" which are arranged side members 10 and fragmentarysectional View on the line 66" another tooth in wheel 19. The

and bywhich chain 17 is moved. On one end of shaft 14 is secured' aratchet wheel 19 designed to be engaged by a springprcssed hook member20 operated by a suitable rod 21 held in place by a guide 22. Pivotallyconnected with red 21 is a lever 23, which in turn is pivotallyconnected at 24 to an adjustable bracket 25 mounted upon a screw member26. The screw member 26 is supported on a ban er 27 rigidly secured tothe carriage 8, an is permitted a free rotary movement, but is notpermitted a longitudinal movement. Upon the rotation of shaft 26 by thethumb member 28,

7 bracket 25 will be adjusted back and forth according to the movementof the shaft 26, the same being threaded, and also bracket 25 beingcorrespondingly threaded. The connecting pin 24 on bracket 25 projectsthrough a slot 29 in the arm-.23 so that the bracket may be easilyadjusted relatively to the arm and thus cause a" greater or less throwto the pawl 20. In order to cause a proper pivotal movement to lever 23,the same is connected with a double acting lever or walking beam 30 bylink 31. The double acting lever 30 is ivotally mounted upon thedepending portion 32 of member 27' so that the same is carried back andforth with the carriage. A link 33 is pivotally connected at one end oflever 30 and is also connected with the stop 34 pivotally connected tothe bracket 35. The stop 34 is adapted tobe in the path of movement ortravel of a lug 36 secured to chain 37. The lug 36 continually remainsin slot 38 in the depending portion 32 of member 37 and thereby movesthe carriage 8 back and forth as the chain 37 moves. As the linkcarrying the stop 36 moves around the sprocket wheel 39, stop 34 will beoperated, whereby lever 23 isgiven a movement in one direction and theratchet wheel 19 (Fig. 1) is moved a step forward a predetermineddistance. In its downward travel projection 36 strikes against a pivotalstop 40 and moves the point thereof downwardly and link 41 upwardly,whereby the lever 23 is moved back to its original elevated position andpawl 20 is caused to engage arts remain in this position until the inkcarrying projection 36 passes around sprocket wheel 42, whereupon stop40 is actuated so as to cause rod 21 connected with lug 23 to movedownwardly and cause pawl 20' to move, ratchet wheel 19 another stepforward. The continued upward movement of the projection 36 will causethe same to strike against stop 34 for-resetting lug 23 and associatedarts. If desired, a spring 43 could be use to reset the various arts. Bythis construction and arrangement it will be observed that as thecarriage is-moved back and forth, chain 17 (Fig. 2) is moved forwardstep by step, a movement of chain 17 occurrin for each movement of thecarriage 8. T is will allow the knife 44 to cut a slice upon eachmovement of the carriage.

Theknife 44 is constructed preferably very thin and with a double edge,each edge bescalloped or formed in waves so as to better seve'r or cutthe meat. The knife is of the endless variety and is arranged to travelupon idlers'45,-46, 47, and 48, and upon a driver 49. These wheelsguidethe knife in bear thereon when the knife strikes the meat. The knife isintended to be moved at a comparatively high speed so that the sidepressure will e very small and will not force "the knife from itscorrect position on the various supporting and driving wheels.

'A suitables ipport or crane 53 is provided for the wheels 45 to 48inclusive, so as to hold the same in proper place and yet allow a properaction of the discharge portion 54 of the carriage 8. In connection withthe drive wheel 49 for the knife, it will be observed that the same ismounted upon shaft 55 (Fig. 7) which shaft also carries worm 56, powerpulley 57, and idlers 58 and 59. The shaft 55 is supported by suitablebearings 60 and 61 so that the knife may be easily placed upon wheel 49and removed therefrom without molesting the driving parts. The worm 56is designed to mesh with a worm wheel 62 so as to drive the samesimultaneously with wheel 50, but at a slower speed. The worm gear 62 issecured to shaft 63, to which is rigidly secured a pinion 64 meshingwith gear wheel 65. A pinion 66 is igidly secured to the same shaft asthe gear wheel 65 that power may be transmitted to the sprocket wheel67. The gear wheel 67 is'loosely mounted upon the shaft 63, but hasrigidly secured thereto sprocket wheel 42, which carries chain 37. Inthis way when power is transmitted through belt 68 to power wheel 57 theknife will. be driven at a high rate of speed. while the carriage 8 willbe moved back and forth comparatively slowly.

From Figs. 1 and 2 it will be observed that the portion 69 of carriage8'is provided with a plurality of slots 70 in which are arranged spikerollers 71. These rollers are designed to be made of an appreciableweight so as to engage the meat and hold the same on the spikes 72arranged on chain 17. This will allow the chain 17 to feed the meatpositively toward. the knife 44.

clamps to the flanges 7 9 on the sides 10 and 11. It will be observedthat the. sides 10 and 11 not only merge into the flanges 79, but alsomerge into and form a bottom in which'a slot 81 is provided'foraccommodating chain 17.- c

In the portion 54 is arranged a pairof rollers 82 and 83, on whichis'mounted an endless belt 84 designed to receive the sliced meat. Afollower 85is placed on the belt 84 and is adapted to prevent thefalling over of the sliced meat so that as the successive slices are outofi, thesame will remain in their original vertical position. As thepiece of meat is being gradually cut or sliced, part thereof will pressagainst the follower 85 and move the same gradually toward the dischargeend of portion 54. The follower 85, as shown in Fig. 5, is providedwithare shaped grooves 86, in which dove-tailed set screws 87 are arranged(Fig. 6), so as to clamp the links 88 and 89 against pivotal movement.Links 88 and 89 form part of the lazy tongs structure 90 carrying at itsouter end a pin 91. The pin 91 is adapted to drop through notch 92 inthe bottom 93 of portion 54 of the carriage 8 when the belt 84 is full.The dropping of pin 91 through notch 92 will cause the same to engagepin 94 arranged on crank 95, which in turn is rigidly secured to shaft96. The shaft 96 is rigidly secured to lever 97, carrying a beltshifting link 98 designed to loosely surround belt 68. When pin 91strikes pin 94 and the carriage moves in the usual manner, the pin 94will be moved laterally with the carriage and will turn or rock theshaft 96, which will move longitudinally link 98 and move the belt 68from the fixed pulley 57 either to pulley 58 or 59, whereupon themachine will stop. Where a short piece of meat is being out, the thumbscrews 87 (Fig. 6) are adjusted so as to lengthen out the lazy tongs 90in order that the pin 91 may drop through slot 92 as soon as all of themeat is severed. In this way various sized pieces of meat may be placedin the machine and severed, the machine being given no attention afteronce being adjusted.

In order that the knife 44 may be properly maintained in a cleancondition, a pair.

of rollers 99 are provided, and also a pair of rotary bristles 100(Figs. 1, 8 and 9). The rollers 99 are designed to clamp the knifeyieldingly under the action of the spring 101 while the bristles 100are'held against rotary movement normally by set screws 102. The bearingfor rollers 99 is he clamps 73 are formed with vidmg t cut the meat.-

elongated slightly to allow I a slight back and forth movement, asclearly shown in Fig. 8. These rollers are mounted upon adjustablesupporting members 103 and 104, rigidly clamped by any desired means, as

for instance set screws, to the extension 105 from the hanger" 53. Bypros cleaning mechanism at this point, the edge of the knife is keptperfectly clean and will properly engage and projecting 1 It will beobserved that in adjusting the lean 44, the Shaft 44. (Fig. 1 may beadju'sted by set screws 45 so as to'fegulate the tension of the bladeand to cause the same to be maintained tight at all times. This is anadvantage where a blade accidentally breaks and is secured together, asthe adjustment may be made for compensating for the'shortening of theblade.
